Abstract Industrial drying may prove to be an economical application of solar energy when the process utilizes stored energy when sunshine is not available. A simple system has been evolved in this laboratory, wherein a reservoir and heat exchanger have been incorporated. Solar heat collection and storage is effected by thermosiphon action with water.

Waste and Biomass Valorization, 2020
A comparative study to the performances of the drying bed and the draining greenhouse was made in summer and winter. During each season, the first experience was conducted in the drying bed. The two other experiences were carried out in the draining greenhouse under natural and forced convection.

Drying Kinetics in Solar Drying
2017From ancient times foods such as fruit, vegetables, meat or fish were dried by direct sunlight. The use of the sun as energy source is advantageous from the economic as well as environmental points of view. However, this procedure has many disadvantages concerning the efficiency and product safety and quality.

Abstract The heat and mass transfer analysis of grain drying for a prototype model is described and the results of a parameter survey showing the effects of various system parameters on drying time are presented. The unique feature of the prototype considered here is that the dryer unit itself serves partly as a solar collector.

Solar drying vs. open sun drying: A framework for financial evaluation
Solar Energy, 2006Initiatives towards large-scale dissemination of solar dryers for drying of agri-produce face severe competition from the largely prevalent practice of open sun drying in most of the developing countries. Therefore, solar drying systems must offer exceptionally attractive financial gains to enhance their acceptance among the potential users.

ABSTRACT The drying of Sultana seedless grapes was investigated under intermittent and continuous operating conditions in a laboratory solar installation involving a thermal storage bed and an auxiliary heater. The effect of pretreatment, and of the a i r velocity on the drying rate of the grapes at constant temperature was also studied in relation t o

ABSTRACT Mass losses and low quality are the most serious disadvantages of traditional grape drying methods. For the production of high quality raisins an increase in the drying rate is required and the grapes should be protected from rain, dust and insects during drying.

The developing countries suffer heavy losses of food in the post harvest period during which the harvested crop passes through a series of well defined steps - like threshing (or shelling), drying, storage and final plrocessing (Fig. 1). Drying is one of the most important steps of post harvest handling of the crop.

ABSTRACT Importance of Solar Drying is increasing worldwide, especially in areas where the use of the abundant, renewable and clean solar energy is essentially advantageous. In the developing countries and in rural areas the traditional open-air drying methods should be substituted by the more effective and more economic solar drying technologies.
